How many HC's do you generally get out of them before they go to the dumpster?

I know one person that gets 30, others tell me the dump them after 8-12.

While I'm not concerned about winning a DE, I don't want to get a surprise where the tire no longer has grip in a bad place from being "chemically" worn out. It's just not worth it.

Hoosier says 16... I've got 17 on my current set and there is still plenty of tread. I hate to pitch them but I also don't want to take any chances.

On a side note, the person that gets 30 out of them runs them at fairly low temps. 30 all the way around. I tried it this weekend. They are squirmy on the first two laps and then settle in nicely. I liked it and the wear doesn't seem any worse than at their recommended 34-36. Average tire temps coming in were around 140ish which is a little low compared to their optimal range chart. This may explain why he gets longer life as the tires aren't getting as hot as what they probably would at higher pressures.

Having tread left is no in any way indicative of how much life there is left on these (talking only about R6's here). Nimber of cycles depends on a large number of factors: car, weight, aero, suspension, alignment, driving style, pace, track surface(s), weather conditions, and so forth. As for getting a surprise, they ar enot like thet: they will continue to fall off at a fairly constant rate until either you just can't get they warmed up & grippy on the out lap or they cord, whichever comes first.

Id like to fall over the edge of the cheeks on your avatar for 17-20 heat cycles Veloce raptor

Run them until wires are sticking out of them and just adjust your driving style as the wear

I'm one of those freaks that keeps detailed logs about my GT3 and DE days, as well as I "overmaintain" my car.


I only started running Hoosier R6's last year so I only have limited data to share with you.

1. 1st set of R6s: 13 Heat Cycles, 436 miles (317 Track/119 street) 185 track miles at Roebling Road with Izzone, and 132 were at CMP


2. 2nd Set of R6s: 12 Heat Cycles 538 miles (304 track/ 234 street), All track miles were at CMP


Keep in mind that all those street miles counted as some heat cycles as I drove this car to work on some sunny days. I DID NOT count the street heat cycles in the above calculations. All of those HC are purely from the track.

Also, I believe others could have gotten another 4-5 HC out of these tires. Once the tires drop off to the point where it isn't very fun to me because of slower lap times and sloppy handling, I go ahead and change them. Otherwise I feel like I am "wasting" my other precious resources such as time , gas, mileage, car, brakes, etc..... out there.




Hope this helps.

P.J.S.

I agree with docdan's data
After 12 heat cycles the are past their sweet spot but they can still be driven if you choose to... But docdan brings up a great point in whether or not that is diluting the "pleasure" of track driving

Mich slicks are worse in that regard although I find the mich slicks even after 10 hc to be better than new Hoosiers in both feel and lap times

I like your style : ). Great way to learn car control just go alittle slower. I run them til they cord. Mike

That's what I did with R6 and still do with RA1.

I think the overall general consensus is 12 to 16 HC on the rear and 16 to 24 on the front depending upon temp, track and driver.

I don't think VIR is too bad on tires and I get 12 on the rears and 16 on the fronts with temps 80 to 90 degrees.

I start with 22 in the rear and 24 in the fronts and finish at 32. If you run higher pressures you'll slide around too much and wear them out even faster.

P.J.S.

I generally replace Hoosier when I am asking myself during a visual inspection if I think they will last another session

I also get pretty even wear front to rear so I generally change all 4 at the same time

I may be giving up a hc or two on the fronts but I like hitting the track with 4 new tires if it is reasonable

Nick Wong

$100K+ car. $2K in tires (max). I think the math is pretty simple, and I agree with you on the replacement logic.

tripleblack

16-24 for DE depending on:
- whether they were heat cycled properly first (>48 hr wait after first session)
- flipped or not (I flip mine at 5-8 sessions / cycles.
- track
- speed
- temp
they start to fall off progressively after 12. +1 for visual inspection. +1 for changing all 4. if you let a pro in your car they'll be done in 10-12 cycles

Fritz Flynn

Yep

I've only been through 2 new sets and didn't bother running the fronts out just giving them a visual and seeing how much tread is left versus rear.

Sure I could go another 4 heat cycles on the rear and cord them and basically use up the fronts but at that point you're 3 or 4 seconds slower and the car doesn't feel nearly as good so as DocDan said there comes a time when you're just wasting time, gas and brake pads.

Veloce Raptor

Meh. Who cares in a DE if you're 3 seconds slower if you learn a bit more about car control?
